Yeah, trust me that it's not a response I ever want to give a user, but this specifically is unfortunately completely out of my control aside from switching to another licensing software provider, and that's unlikely to happen due to the immense switching cost, both for me and for all existing licensed IC2 users.
If you'd like I can connect you with someone from the licensing software vendor to see if any other options are available, but in my experience their response is going to be the same...update Windows and the network interface drivers and makes sure that they're all enabled for license activation.
If you do want to get a discussion going with the vendor, reach out to me
directly and I'll be happy to facilitate that.
